Indeed: 'lefa'-bound.

The following items are bound in 'lefa' - made from leftover leather pieces and latex - often found in toe-caps and insoles. Lefa is ideal for notebooks, it is pleasant to hold and easy to grip. We are the only firm to use lefa in this way. The cover is not treated and takes on a patina with use - so you can see how important it is to its owner! The paper is some of the best on the market: 192 pages of chamois writing paper. The section sewn books have a ribbon marker.
